Yes, they can, but they probably will be hiding and won't flash.
Can fireflies be out during the day instead of night without dying?
Yes
Fireflies appear at night time, when it is dark.
Because they're nocturnal insects, fireflies [Lampyridae family] tend not to come out during the day. They prefer the pollen and the insects that they find at night. Additionlly, they use their lighted abdomens as part of their mating procedure. The abdomen may be lighted during the day, but not sufficiently visible or attractive to the opposite lightning bug sex.
Fireflies love warmth, so they come out during the summer months. You can start seeing fireflies in June, July and August, but they have a short life span.
Fireflies can be found in the southern and midwestern sections of the United States.
At night is the time during which fireflies [Lampyridae family] eat. They tend to be nocturnal insects. But that doesn't guarantee that they'll be seen feeding. Adult fireflies may choose to eat plant pollen and insects. Or they choose not to eat at all.
Fireflies will fly close to dawn. As the sun crests in the East, you'll see less of them, until they're gone. Normally, fireflies will sleep in bushes, gardens, hedges, just about anywhere they can catch warmth. July is the best month to see them in clusters. It's said that the firefly will " flash" for the last time just before dawn, and don't come out at night until the sun is ready to set.

Yes, there are fireflies in Spain, particularly in certain regions during the warmer months. They are commonly found in areas with lush vegetation, such as forests and wetlands. Fireflies, or lightning bugs, are most visible during late spring and summer evenings when they use bioluminescence to attract mates. However, their populations can vary due to environmental factors.
